Looking for Transmission harness connector
 

So to make the long story short, I have a P0746 and my mechanic said it was my electrical connection to the transmission that was corroded and throwing errors. I can't for the love of me find it anywhere. Every single junkyard he called the wire is totally corroded. I have a 2009 Mitsubishi Outlander, and has anyone dealt with online part pickers from west coast? I live in the Rust belt and trying to find non rusty and non corroded electrical is an absolute nightmare.
